39

Step-by-step explanation:

Let's first take the ones with numerical values into play. If you add the second and the third equations, you get 10 = 2(shoe), so the shoe is 5. Then the helmet is 4. Taking the first equation, shirt-5=4+4, so shirt = 8+5=13. Then, we have Goal post = 4+13=17. The question mark is 13+9+17=39.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
